APPLICATION INFORMATION
Some applications have two energy sources, one of which should be used in preference to another. Figure 14
shows a circuit that will connect IN1 to OUT until the voltage at IN1 falls below a user-specified value. Once the
voltage on IN1 falls below this value, the TPS2112A/3A will select the higher of the two supplies. This usually
means that the TPS2112A/3A will swap to IN2.
Figure 14. Auto-Selecting for a Dual Power-Supply Application
In Figure 15, the multiplexer selects between two power supplies based upon the EN logic signal. OUT connects
to IN1 if EN is logic '1'; otherwise, OUT connects to IN2. The logic thresholds for the EN terminal are compatible
with both TTL and CMOS logic.
